Reviews for Graphing Calculator Plus (X84)

I recommend this app to all of my statistics students. So, thank you and keep up the good work! I do have a request, though. Is it possible to add a feature to change the bin size for histograms? Right now, you can zoom in and out, but doing that does not change the bin size. Thank you again for your fine work!

Awesome calculator! I reviewed plenty of free apps. I really did not want to spend any money. I am so glad I did for this calculator. It was well worth the small investment. Buying this version has made my statistics class so much easier!

Works well half the time, but I constantly run into issues where the Y= menu quits receiving inputs, so you are unable to clear, delete or edit any lines. I would also like to be able to set the graph grids to whole numbers, instead of random decimals.

The app needs some work. The Stat Wizard of TI-84s is missing, so it functions like a TI-83. I do like how the graphs take advantage of pinch to zoom. To be blunt, wabbitemu is ahead of it as far as an emulator goes, but this app is still usable.

The keys are sticky. Maybe it is just me. Does the screen scroll up? Somehow, the active cursor is not going to a new line for me. I just clear the screen, it is not a problem. This app is equivalent to the TI-84 graphing calculator. Very, very good. Thanks. Great price.

As far as I can tell, this has all the functionality of the TI 84 calculator. For heavy, day to day use, I still prefer the physical calculator; the real keys make the work much easier, error free. However, for occasional use, and at a low price, this is a good deal.

Have had this app on every one of my phones since 2018, absolute essential if you ever do more than just simple calculations, but even then it's still useful to have a history of previous operations. I gave this app a 3 star back in 2018 because I thought there was an issue with the way it calculated - devs responded the next day and told me the error and how to input it correctly to get the answer I desired. Definitely worth buying the full version!

Very nice calculator, however, the arrow pad buttons are too small, which results in accidentally pressing "Clear" when navigating the cursor around equations. It's very frustrating to accidentally clear a long equation after spending time entering it in. Please add more padding to the up and down arrow buttons.

Honsetly: Form a College Student This is so helpful! It good to have if your taking math or science classes, or any class you need a calculating. You know, for problems that won't cut it with the calculation you have one your phone. This is it. And best part CHEAP! Some of the one you get on hand, like to go buy/use it, are so expensive. Yes their hard and your can carry it with you to every class and hope you never loss's it because, YOU GOT TO BUY ANOTHER ONE. This one nope buy it's once

My first time using this calculator. It followed the Ti84 manual closely. There are a few differences like the zoom button being exchanged for a more powerful button. The zoom can be accomplished by pinching. I wish there was a way to lock in a square axis however.

Never had any graphing calcs in my life but it has now become sort of necessary so o decided to look around the store aand found the. free version of this, looked through this and that and decided to spend the 5$ for it. Absolutely worth every penny, considering the alternatives' prices in stores. Definitely don't regret buying it and for anyone worried about it being locked to a single device, don't worry the purchase is in your apps drawer/list or whatever so you can install it on all devices

(FYI, I have a paid version as I intend to use this app often. ) I was programming on this calculator and got stuck at some syntax error. I clicked "2ND" button and press "?" button on the bottom left of the calculator which gave me option to email my questions by using "Support email". They got back to me promptly less than 6 hours. The email was very helpful and I fixed the errors right away. I would highly recommend this app.

The Best calculator, but it has a learning curve. I use this calculator at my work, ap physics, and ap calculus, and it is the best out of any other calculator program that I have installed. I would like to ask the developer: "how would I get the lines on the graph to be whole numbers?", and also: "please add more color themes, or a higher contrast black. Custom UI colors would be amazing". This app is well thought out, and it is just so amazing, so thumbs up to the devs.

It is not working good. This TI-84 Plus calculator either do not go the same way as the real TI-84 or it cannot be complete the task. On trying to plot a graph, It takes me to the icon of graph but it doesn't go to zoom. There is no "zoom" . Also, when I enter a number of sevral digits and try to delete only one digit of it or to replace it with another digit, there is no backspace button, so I must go to format at the 2nd field and chose "clear data" to reset the calc for a new problem.

I can't stress enough how streamlined the ui is in the app. It's so much faster than the regular (150 dollar) calculator, and is in color. Tracing lines on the 2d grid is so much faster and less tedious, going through menus is so much more intuitive, and the speed of all of the calculations are lightning fast. For 4 dollars, this BETTER IN EVERY WAY calculator is an absolute steal of an app. It's like upgrading from a flip phone to a next gen phone, cheaper than the flip phone. Get it!!!!

What a fantastic app! I upgraded to the premium version, and so glad I did. It works exactly like my TI84 Plus CE, but with more functionality and portability. The only thing I noticed that I don't like is that the delete (DEL) button works like a delete button, but without the hilighting cursor (the app has a traditional blinking line cursor) it is very easy to forget that it is a delete button, and not a backspace. It matches the calculator perfectly, just takes a little getting used to.

I really believe this is by far the best calculator I have used so far. Beautiful u.i. along with the awesome quick access feature . The only criticism that I have is: 1: Copying typed equations into a clipboard and to be able to paste number values from the phone's native clip board would be a nice feature to have. 2: Automatically place negative numbers in parentheses when using exponents. 3: When scrolling through previous calculated entries, you end up with a very small window to enter new equations in with previous entries stacked on top of one another without the ability of resizing it back to it's original size. 4: Would be nice to have the history memory larger. Say from 25 to 100 entries. I am still gonna give this 5 stars because I really like the work you guys have done overall. Overall I am glad I paid for this and would gladly recommend to others. Great work on this developers!

I can see why people like it, but it is not user friendly. I have yet to get the graph feature to work. I love the black theme and how the buttons are wider so less miss clicks, but using it for my stats class has been an nightmare. I wish there was a free trial so I didn't waste money since using the app is cheaper than buying an actual TI 84 Plus. As a student, I don't really need throwing out money on apps that are not useful.

Fantastic calculator! Just like a TI-84, except better! So far I've found a periodic chart of the elements, added commands that allow you to look up atomic properties from the normal calculator screen, like ability to control the graphing screen with touch, built-in conversions, several physical constants, everytime I turn it on I find something new. Great job, developers! I hope you add even more features.

This is a faithful TI-84 emulator and so far I have not run into any problems. A shortcoming is less than adequate documentation, no "about" to show version number, and no statement that it's trying to be a TI-84 vs 83,85 or whatever. 4.5 stars. If you want a graphing calculator on your phone, this is a good one. Add free once paid for.
